Answer 3

Heat acid to different temperatures(1)

Use the same size of agar jelly cubes(1)

use same volume of concentration of acid(1)
measure clear distance from outside of the cube at each temperature(1)

Question 4

Answer 4

Diffusion through the water(1)
so water moves through xylem
by transpiration steam
into leaves by diffusion(1)
